C++ debugging can execute code due to mouse hovering over code

[unpacklo]

Type: Bug

When debugging C++ code it's possible to be sitting at a break point and the mouse hovering over a function can cause it to execute. This can unintentionally break debugging sessions due to unintended mouse movements.

[unpacklo]

This code can illustrate the bug:

#include <cstdio>

struct incrementer
{
    int i = 0;

    int increment()
    {
        return i++;
    }
};

int main()
{
    incrementer i;
    i.increment(); // Set breakpoint here, then hover mouse over "increment()", watch i.i change value.
    printf("%d\n", i.i);
    i.increment();
    return 0;
}

@unpacklo Is this with gdb or lldb?
